win32: improve filesystem detection and display

Miscellaneous improvements:

- Enable '-a' option to display all filesystems in df(1).
- Detect the UDF CDROM filesystem and display it in 'stat -f'.
- Let getmntent(3) handle CDROM and floppy devices, ignoring those
  that have no media.
- Set number of inodes and filesystem flags to 0 in statfs(2).
